They’re not cheap or inexpensive!
I feel you do get what you pay for sometimes ,
I think in all honesty that a lot of its down to the operater, if you look at some of the early clocks and at the equipment they were made with !
A good example is the amount of backlash in the feedscrews on an older lathe, if the Turner knows their machine a half turn won’t stop them producing wonderful work , but a poor workman will complain all day long about it preventing them from first class work . . .
